Drummer apl.de.ap recently gushed about the mom-to-be while being honored at the Time for Hope Gala in Beverly Hills.
"It's mama time, it's Ferg time right now," the musician told E! News at the event before heading to AV Nightclub. "It's about the baby and her and Josh and the family now."
The group known for their huge hits including "Where is the Love," "Pump It" and "I Gotta Feeling" are currently taking a "vacation" as Fergie and her husband, Josh Duhamel, prepare to give birth early in the fall.
"We don't want to put any stress," apl.de.ap said. "I love you Ferg. I love you."
